Hi ! I'm experiencing a major problem since installing version zcs-8.7.11_GA_1854 on UBUNTU 16 64 bitWhen I start the zimbra, it already allocates 3.5 GB and during the day continues to increase the used memory. My server had 8 GB of memory and I recently upgraded to 16 GB of RAM. I currently have approximately 250 active accounts. The available memory goes down gradually, and when it finishes the load aveage arrives at very high levels and it catches the whole server.In rare moments, free and available memory increases.
